Not really bullying, but in year 3 (That's third grade, I think? XD) we had this supply teacher...

Basically, my mum worked at my primary school, and when this supply came in, she really didn't like me for some reason. There was no reason for it either, I was always a goody two shoes and I never got a detention or anything like that!

Anyway, at every single opportunity she could get, she would shout at me, ask me to stand up in the middle of class, and I wasn't allowed to sit down! She kept saying, "I've heard your mum works at the school, I'll tell her you've been bad" and things like that

Its a pity my 8 year old self was too dumb to realise what was happening, I'd give her something to reason with if it happened now!

I remember in 2nd or 3rd grade elementary, the yard duty teacher made me and my friends sit on our hands on the pavement in a very hot day--that was our punishment for throwing sand at each other, we were playing around. We were just kids for christ sake.

I had every right to sue.
Looking back now, this was outright child abuse.

Having an 8 year old, sit on his hands (hands under butt) in a hot day, on the black pavement, during lunch time (30 minutes).Torture. I remember it hurt too. The little rocks digging into my hands, bleeding a little...

I don't really know if it's really considered "bullying", but I had extremely hard times with my teachers in middle school. They were all pretty bad at their job, they didn't pay very much attention and tended not to bother with their students; getting kids in trouble for doing nothing. I don't think I ever felt bullied, just annoyed with them. They never really liked me, I guess that's something.
